Vim yog tus nqi siab ntawm tantalum, kev txhawb nqa clamping qhov chaw ntawm cov evaporation qhov chaw thiab cov evaporation qhov chaw uas nyuaj rau tsim tag nrho yog feem ntau fabricated los ntawm sectional forming thiab ces welding tag nrho. Tantalum yog ib qho yooj yim heev rau oxidize ntawm qhov kub thiab txias, tsim ib qho kev daws teeb meem thiab intermetallic compound, uas ua rau muaj zog thiab hardness, tab sis txo qis hauv plasticity thiab toughness. Nws yog ib qho yooj yim los tsim coarse nplej, tsim pores, thiab tawg, thiab ua rau muaj teeb meem loj hauv vuam. Tantalum muaj thermal conductivity thiab xav tau lub zog loj rau vuam, tab sis nws yog ib qho yooj yim los ua coarse nplej thaum lub vuam kub input loj. Lub vuam cua sov input yog me me heev rau qhov tsis zoo melting ntawm lub pas dej molten. Yog li ntawd, welding cua sov input yuav tsum raug xaiv rau lub vuam ntawm tantalum los xyuas kom meej qhov zoo ntawm cov vuam.
Tam sim no, lub ntsiab tantalum welding txoj kev nyob rau hauv lub ntiaj teb no muaj xws li inert gas tungsten arc vuam, laser vuam, electron beam vuam, thiab tawg vuam, thiab lwm yam. Vim qhov yuav tsum tau ntawm tshav kub-tshem tawm tsam lub koom haum kev cai, siab zog ceev laser vuam, thiab electron beam welding tau dhau los ua txoj hauv kev loj vuam tam sim no.
Inert gas tungsten arc vuam tau maj mam hloov raws li thawj tiam thaum tshav kub kub qhov chaw vim hais tias ntawm nws qeeb kub nce thiab yooj yim tsim ntawm loj tshav kub-tshwj xeeb cheeb tsam qauv nyob rau hauv high-kub theem. Vim qhov nyias nyias ntawm qhov chaw ntawm qhov chaw evaporation, cov txheej txheem vuam yog qhov yooj yim rau deformation thiab vuam vim yog melting ntau dhau, yog li laser vuam yog ib txoj hauv kev zoo dua rau tantalum evaporation qhov vuam.
